Future Network :

Broadband-PPDR

Spectrum needs and solutions

Riding the (RADIO)waves of change

Bucharest, September 26th, 2016

2FM49 was created in 2011

The approach

• Definition of use cases and deployment scenarios

• Identification of spectrum ranges to be studied (400 and 700MHz)

and amount of frequencies necessary

• Identification of applications within and in adjacent bands (PMR,

DTT, MFCN , radars …)

• Compatibility and feasibility studies

• Produce the regulatory framework including technical conditions to

ensure a safe use of the band by BB-PPDR

• Inform ETSI and 3GPP about the regulation for the standardisation

ECC Report 199 - User requirements and spectrum needs for

future European broadband PPDR systems

• Need for interoperability between European PPDR organisations

• Use of common technology improves international cooperation

• Use of LTE for economy of scale

• PPDR application related requirements presented in a form of a

matrix developed by LEWP/RCEG.

• location data, multimedia, office applications, download operational

information, upload operational information, online data base enquiry…

• vs throughput p/s per session, number of users, mobility (using while

moving)…

ECC REP 199:Spectrum needs for three operational environments:

• day-to-day operations (category “PP1”)

6

ECC REP 199: PP2 & DR

• large emergency and/or public events (category “PP2”)

disasters (category “DR”) –(the spectrum requirements for PP2 cover

the early needs of a DR event (this is a simplifying assumption)).

7

ECC Report 199: conclusions

• It is considered that 10 MHz of spectrum for the uplink and

another 10 MHz for the downlink provide enough capacity to

meet the core requirements of the PP2 scenarios. This may

vary on national basis.

• However there could be additional spectrum requirements on

a national basis to cater for Direct Mode Operations (DMO),

Air-Ground-Air (AGA), ad-hoc networks and critical voice

communications over the WAN.

• The frequency ranges selected are 400 MHz and 700MHz

8

ECC REPORT 218 : TECHNOLOGY ASPECTS

• PPDR should be part of the global LTE ecosystem:

• more choice of terminals,

• lower prices,

• roaming with commercial networks

• and long term further developments.

• Noting that the work on developing the LTE technology to

support the PPDR specific functionalities (Push To Talk, DMO

…) has already started in 3GPP.

9

ECC REPORT 218 : IMPLEMENTATION OPTIONS

• Dedicated network infrastructure for PPDR

A specially designed mobile broadband network (either owned

by the government or contracted operator) for BB-PPDR to meet

the specified requirements (coverage, support of special

broadband applications, resilience, security etc.).

• Commercial network(s) infrastructure

The governmental authority will buy mobile broadband services

from one or several commercial mobile network operators, with

or without special requirements.

Hybrid solutions

• Partly dedicated and partly commercial network infrastructure 10

ECC REPORT 218 : INTEROPERABILITY AND CROSS-

BORDER COMMUNICATIONS

• Interoperability is to be realised on multiple layers

through:

• the availability of multi-band BB-PPDR UE

• the adoption of common technical standards (i.e. LTE and its

evolutions – base standards and specifications),

• for solutions across the different BB-PDR networks solutions

(dedicated, commercial or hybrid networks),

• and also by standard conformance and interoperability

specifications.

• It is not required to designate identical (harmonised)

frequency bands for broadband PPDR in every country.

11

ECC REPORT 218 :CONCEPT OF “FLEXIBLE HARMONISATION”

ECC decided to use the concept of “flexible harmonisation”

to enable an efficient implementation of BB PPDR within

CEPT.

• common technical standard (i.e. LTE and its evolutions)

• national flexibility to decide on how much spectrum

should be designated for PPDR within harmonised tuning

range(s), according to national needs

• national choice of the most suitable implementation

model (either dedicated, commercial or hybrid)

12

ECC DEC (16)02 - Harmonised technical conditions and frequency

bands for the implementation of (BB-PPDR) systems

13

• Bands for which technical conditions have been defined

are (with channelling arrangements 1.4 MHz, 3 MHz or 5

MHz) :

• 700MHz

• 698-703 MHz (uplink) / 753-758 MHz (downlink)

• Within 703-733 MHz (uplink) / 758-788 MHz (downlink) with

conditions specified for MFCN

• 733-736 MHz (uplink) / 788-791 MHz (downlink)

• 400MHz (frequency range)

• 450.5-456.0 MHz (uplink) / 460.5-466.0 MHz (downlink)

• 452.0-457.5 MHz (uplink) / 462.0-467.5 MHz (downlink)

CROSS BORDER FREQUENCY COORDINATION

• CEPT/ERC T/R 25-08 on the planning criteria and

coordination of frequencies in the land mobile service in

the range 29.7-470 MHz is under revision and will now

address BB-PPDR.

• ECC/REC/(16)03 on cross-border coordination for

Broadband Public Protection and Disaster Relief (BB-

PPDR) systems in the frequency band 698 to 791 MHz

(final approval in October 2016)

14

Commission Implementing Decision (EU) 2016/687

• Within the 703-733 MHz and 758-788 MHz frequency bands:

“Without prejudice to the right of Member States to organise and use their

spectrum for public safety and public security purposes and for defence, if

PPDR radio communications are implemented, the technical conditions for

wireless broadband electronic communications services in this annex

should be used.”

• “The frequency bands 703-733 MHz and 758-788 MHz, or a subset thereof, may also

be used for PPDR radio communications. “

• Therefore when using BB-PPDR within the MFCN bands, MFCN least technical

restrictions must be used.

• 2016/687/EU does not apply technical restriction in the 698-703 MHz, 733-736 MHz,

753-758 MHz and 788-791 MHz bands. This is covered by ECC Decision (16)02.

(http://eur-lex.europa.eu/legal-content/EN/TXT/?qid=1464706780910&uri=CELEX:32016D0687 15

OTHER USE CASES (CRITICAL VOICE, DIRECT MODE, AIR-

GROUND-AIR AND AD-HOC NETWORKS)

• The same frequencies as for the WAN could be used for DMO and

ad-hoc networks

• The report does not provide an indication on alternative options nor a

solution for future PPDR AGA systems.

• The assumption is that mission critical voice will be carried in most

countries by the existing dedicated mission critical voice (+ NB data)

TETRA and TETRAPOL networks for many years (10-15 years). At

the moment for mission critical voice there is a harmonised European

NB PPDR allocation of 2x5 MHz in the 380-400 MHz band.

16

Next Steps…

• Ongoing work at CEPT level:

• Further studies on the band 410-430MHz (no standardized for

LTE yet)

• Possible future revision of T/R 25-08 for the cross-border

coordination in 400MHz based on further technical studies

regarding LTE and CDMA

• Publication of the Recommendation 16(03) on cross-border

coordination for Broadband Public Protection and Disaster Relief

(BB-PPDR) systems in the frequency band 698 to 791 MHz

• 3GPP work !!

• The regulation is in place

• 3GPP is starting to work on the standardization for 700MHz BB-

PPDR equipment but needs to also trigger the 400MHz work.

• Production of an HS via ETSI 17

National case : France

• France has already allocated 2*5MHz and 2*3MHz in the

700MHz band to Ministry of Interior for BB-PPDR.

• Protection of DTT below 694MHz via a power limit of 23dBm

for the terminals and a restriction of out of band emission

below 694MHz to -42dBm/8MHz under normal conditions and

relaxed to -30dBm/8MHz under extreme environmental

conditions.

• There are ongoing national work to identify a further block of

2*3MHz within the 451-456MHz paired with 461-466MHz for

BB-PPDR.
